Abstract
Abstract A color television receiver includes a comb filter having luminance and chrominance outputs coupled to respective inputs of a display processor. A signal source provides composite and non-composite color video signals for display. A switching circuit having a first operating mode for coupling the composite video signal to an input of the comb filter for enabling display thereof by said display processor. The switching circuit has a second operating mode for coupling the luminance component of the non-composite video signal to the input of the comb filter and for concurrently coupling the chrominance component of the non-composite video signal to the chrominance output of the comb filter for facilitating display of the non-composite video signal by said display processor.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
132 words
A color television receiver, comprising: a comb filter having luminance and chrominance output coupled to respective inputs of a display processor; a signal source for providing a composite video input signal having combined luminance and chrominance components and for providing a non-composite video input signal having separated luminance and chrominance components; and circuit means having a first operating mode for coupling said composite video signal to said input of said comb filter for display by said display processor and having a second operating mode for coupling said luminance component of said non-composite video signal to said input of said comb filter and for concurrently coupling said chrominance component of said non-composite video signal to said chrominance output of said comb filter for display of said non-composite video signal by said display processor.
Claim 2
Dependent Claim
132 words
A color television receiver, comprising: a comb filter having luminance and chrominance output coupled to respective inputs of a display processor; a signal source for providing a composite video input signal having combined luminance and chrominance components and for providing a non-composite video input signal having separated luminance and chrominance components; and circuit means having a first operating mode for coupling said composite video signal to said input of said comb filter for display by said display processor and having a second operating mode for coupling said luminance component of said non-composite video signal to said input of said comb filter and for concurrently coupling said chrominance component of said non-composite video signal to said chrominance output of said comb filter for display of said non-composite video signal by said display processor.
Claim 3
Dependent Claim
58 words
A color television receiver as recited in claim 1 wherein said circuit means comprises a switch having a first input for receiving said composite video input signal, having a second input for receiving said luminance component of said non-composite video input signal and having an output coupled via an amplifier to said input terminal of said comb filter.
Claim 4
Dependent Claim
66 words
A color television receiver as recited in claim 1 wherein said circuit means comprises first and second switches, said first switch for selectively coupling said composite video signal and said luminance component of said non-composite video signal to said input of said comb filter, said second switch for selectively coupling said chrominance component of said non-composite video signal to said chrominance output of said comb filter.
Claim 5
Dependent Claim
17 words
A color television receiver as recited in claim 3 wherein each switch includes a respective output amplifier.
